    ABSTRACT:: Using backward error analysis, this paper compares the
               roundoff error in the least-squares solution of a system of
               conditional equations Ax=f by two different methods. The
               first one entails solving the normal equations $A^T$Ax=$A^T$f
               and the second is one proposed by Faddeev, Faddeeva, and
               Kublanovskaya in 1966. This latter method involves
               multiplying the system by orthogonal matrices to transform
               the matrix A into upper triangular form.
